BAD SERVICE DISCOVERY HEALTH

I have been a member of discovery for over 15 years. Now suddenly I am told that Discovery will deceide to pay money to the service provide even if they claimed in my self-payment gap to "make my self payment gap " SMALLER. Yet the then send me an account of six and a half thousand rand which is more than my original self payment gap was to start with. Who gave them the right to do that NOT me their client. They are also charging me for a so called debit from 2017 where Discovery made the mistake of paying for something twice NOT my fault I can not see why I must now pay for them making choices for me with out my consent. I am very dissapointed that such a company seems to think that they can do as they please, with a persons money and when you phone the call centre no one is able to give you a satisfactory answer and simply say "you can talk to my manager or take it up with legal to make a repayment plan" not at all helpful when it is Discovery that is actually in the wrongf.
